note 40292 deleted from function.mkdir by aidan

Note Submitter: jkaufman at wamnetgov dot com ---- I modified Shaun's version of mkdir_p slightly. 1) I consider an existing directory a success, not a failure 2) If the file exists and is not a directory, then we have a possible issue and the function returns 0 3) I changed 'eregi' to 'ereg' 4) I simplified the recursive call, eliminating the if statements function mkdir_p($target) { if (file_exists($target) && !is_dir($target)) return 0; // failure if (substr($target, 0, 1) != '/') $target = "/".$target; // prepend a slash if (ereg('\.\.', $target) || ereg("[^a-zA-Z0-9\._\-\/]", $target)) return 0; // if illegal dirname if (mkdir($target)) // if new dir created, return 1; // we are successful if (mkdir_p(substr($target, 0, (strrpos($target, '/')))) == 1) return (mkdir_p($target)); else return 0; }
